If you were a member of my club, and bought all your components on our last club order, this is what your cost would be.
I know a lot of you will not believe me but I've figured mine out to between $4-5 (sometimes less) a box depending. But I am a "Internet Bargain Hunter" I seldom buy any reloading stuff off the shelf. I refurbish and rebuild Mecs as a hobby so often find them in bad shape or someone just doesn't want to reload anymore. And the seller has a bunch of other stuff to get rid of too and I have found some really good deals on powder, primers, shot and hulls. Reciently I bought a used Mec and the guy had a black round metal 14 lb container with 700x on it. It was half filled and he thru it in the deal for $50. Another guy had a 1K box of Rem209P Primers he gave me for $30. Find bags of #7.5 & #8 shot all the time just thrown in the deal because they have no use for it anymore. So you can see how this really cuts down on the cost of reloading. Besides I just like the hunt ! lol And the hunt really pays off since I shoot trap twice a week which ads up to a min of 16+ boxes of shells a month
